| Abstract: | A method to measure the dynamic level in the oil well with screw pump is provided. Sharp sound waves produced at the well mouth transmit along the well hole and are reflected as reaching the oil-gas interface. The paper focuses its main work on sound signal processing and recognition of echoes. The corresponding filters are designed according to the features of the noises in the system. The sound speed in compressed natural gas is obtained by analyzing the echoes from the joint hoops, the echo from the oil-as interface is automatically recognized in the software, and the depth of the well can be obtained. Finally, the measurement error is also analyzed. For the reference depth of 993. 77 m, the maximum error is 23. 33 m. |
